“…The contribution of autotrophic nitrification increased to 69% with increasing N fertilization application. The contribution of autotrophic nitrification to soil N 2 O emission in the lawn soil was higher than previous findings on grassland soils (9-27%) and within the range for agricultural soils (14-95%) in laboratory incubation (Chen et al, 2014;Müller et al, 2014;Duan et al, 2019). These differences may relate to soil carbon content, nitrogen content, soil water content, and pH etc (Chen et al, 2014;Müller et al, 2014).…”

“…Approximately 5 g fresh soil from each sample was placed into 20 ml glass vials (Chromacol, 125 × 20-CV-P210) together with 50 mg soil kg −1 dicyandiamide (DCD, a nitrification inhibitor) and 50 mg 15 N kg −1 NH 4 15 NO 3 (99.26 atom% 15 N, Shanghai Research Institute of Chemical Industry, China) or 50 mg N kg −1 NH 4 NO 3 . DCD and NH 4 15 NO 3 or NH 4 NO 3 were added in solution form (Gong et al, 2013;Wang et al, 2018;Duan et al, 2019). The final soil moisture in each vial was adjusted to 80% of the water-filled pore space (WFPS).…”

“…Most studies have concluded that nitrification and denitrification are the main microbial processes producing N 2 O (Fang et al, 2015;Tang et al, 2018). However, recent studies showed that grassland, temperate forest, and agricultural soils could produce N 2 O through heterotrophic nitrification and co-nitrification, and identified the contribution of heterotrophic nitrification and co-nitrification to N 2 O production (Müller et al, 2014;Zhang et al, 2015;Tang et al, 2018;Duan et al, 2019;Zhou et al, 2021). Heterotrophic nitrification in soils with high organic carbon and nitrogen concentrations and low pH were the main contributors to N 2 O emissions, accounting for 85% of total N 2 O emissions (Müller et al, 2014;Zhang et al, 2015).…”

“…A previous study found that co-denitrification contributed 17.6% of the total N 2 O production in grassland soil (Müller et al, 2014). Additionally, a variety of N compounds involved in co-denitrification are also permitted to be co-metabolized during denitrification (Duan et al, 2019). Codenitrification is a co-metabolic process that uses inorganic and organic nitrogen compounds concurrently and converts them into the same end products as denitrification .…”

As nitrous oxide (N2O) is one of the most important greenhouse gases, N2O emission pathways and regulation techniques in soils with different vegetation types have become a research focus. Currently, a diverse array of research exists on the N2O emissions from soils of different vegetation types, e.g., forest, grassland, and agriculture. Few studies have investigated the microbial processes of N2O emissions from lawn soils. Fertilization levels in lawn soils are often similar to or much higher than those in agricultural ecosystems, thus fertilized lawn is an important source of atmospheric N2O. In the study, we employed the 15N-nitrate labelling method combined with the nitrification inhibition technique to distinguish microbial processes and their contribution to N2O emissions in long-term nitrogen fertilised lawns. We found that the N2O emission rate from the control treatment was 1.0 nmol g−1 h−1 over the incubation, with autotrophic nitrification contributing 60%. The N2O emission rate increased to 1.4 nmol g−1 h−1 from the soil treated with long-term N fertilization, and the contribution of autotrophic nitrification increased to 69%. N fertilization did not significantly increase the contribution of denitrification (24–26%) in the total N2O emissions. However, N fertilization substantially decreased the contribution of heterotrophic nitrification from 13 to 0.4% in the total N2O emissions. Co-denitrification to N2O was detected but the overall contribution was of minor importance (3–5%). The correlation analysis revealed that soil NO3− levels were the main influencing factors in the N2O producing microbial processes. Our results suggest that N fertilization altered both N2O production rates and the contribution pattern of microbial processes, and indicate the autotrophic nitrification and heterotrophic nitrification are more sensitive to N fertilization than denitrification and co-denitrification.

“…Biochar, a solid material obtained from the thermochemical conversion of biomass in an oxygen-limited environment, has attained extensive attention due to its agronomical and environmental benefits in agroecosystems [8][9][10][11]. Regarding to the effects of biochar on N cycling in vegetable production system, many literatures reported its influences on NH 3 volatilization and N 2 O emission from both stable crop and vegetable production systems [12][13][14][15]. Further, Dong et al [16] observed the effect of biochar amendment on N release to percolation water in paddy soil.…”

There are few evidences on the effect of biochar on vegetable yield, nitrogen (N) and phosphorus (P) leaching losses under intensive vegetable production soil. The current field plot scale study evaluated responses of Chinese cabbage (Brassica oleracea L.) yield, N and P leaching losses using five N treatments of common N application rate according to local farmers' practice (N100%), reducing 20% or 40% N fertilizer (N80% and N60%), and reducing 40% N fertilizer but incorporating 10 or 20 t/ha biochar (N60% + BC10 and N60% + BC20). Results showed that N80% and N60% decreased both the cabbage economic and leaf yields by 6.8%-36.3% and 27.4%-37.7%, respectively. Incorporation of biochar with reduced N fertilizer rates improved the cabbage yield, in particular the N60% + BC20 matched the yield that observed in N100% treatment. Enhanced N and P uptake capacities of cabbage shoot probably contributed the higher vegetable production under both biochar amendment schemes. Biochar application mitigated the NH 4 + -N and total P leaching losses by 20%-30% and 29%-32%, respectively, compared with their counterpart treatment N60%. Nevertheless, biochar exerted no influence on the NO 3 --N leaching. In addition, soil organic matter content was recorded with 7.4%-28.7% higher following 10-20 t/ha biochar application. In conclusion, biochar application can increase economic yield of cabbage via increasing N and P use efficiency, decrease N and P leaching losses, and improve soil quality in an intensive vegetable production system.
